Technical Specifications

Pain Points vs. Solutions

Your Challenge: High energy costs in hazardous areas

Our Solution: IE5 efficiency reduces operational losses by 4-7% compared to IE4 motors, significantly lowering your electricity bills.

Your Challenge: Frequent equipment failures in explosive environments

Our Solution: Robust explosion-proof design with Ex d IIC T4 Gb certification contains internal explosions, preventing ignition of combustible atmospheres.

Your Challenge: Excessive downtime for maintenance

Our Solution: Premium SKF/NSK/FAG bearings and optimized heat dissipation extend service life while minimizing maintenance intervals.

Technical Advantages

The YBX5 explosion-proof motor employs advanced silicon steel and winding materials for superior electromagnetic performance. Its optimized heat dissipation rib structure maintains lower temperature rise during continuous S1 duty operations. F-class insulation and IC411 self-fan cooling offer dependable thermal management. Low noise operation with decreased vibration (B-level standard) and IP55 protection (upgradeable to IP66) are features of the design. The motor is suitable for working in methane, ethylene and hydrogen mediums and is compatible with temperature groups T1-T4 for petroleum, chemical, mining and metallurgy sectors.

Production Process

Our manufacturing follows strict quality protocols:

1. Material Selection – Imported silicon steel cores and copper windings from certified suppliers

2. Precision Machining – CNC-controlled component manufacturing with ±0.01mm tolerance

3. Assembly & Testing – Clean-room assembly followed by no-load, load, and vibration testing

4. Explosion-Proof Verification – Individual flameproof joint inspection and pressure testing

5. Final Certification – Comprehensive performance validation before shipment

Industry Applications

The motor serves critical roles across multiple sectors:

· Petrochemical: Driving pumps and compressors handling volatile liquids

· Coal Mining: Powering conveyors and ventilation fans in underground operations

· Pharmaceutical: Operating mixers in sterile environments with solvent vapors

· Grain Processing: Running mills and conveyors in dust-laden atmospheres

· Metallurgy: Actuating centrifuges and crushers near combustible gas sources

Customization Capabilities

We tailor motors to your exact specifications:

· Voltage and frequency adjustments (400V/440V 60Hz for export markets)

· Bearing upgrades to SKF, NSK, or FAG per your preference

· Dimensional modifications for seamless equipment integration

· Special shaft extensions and mounting configurations

· Custom painting and environmental protection coatings

Direct interchangeability with YBX3/YBX4 series eliminates costly equipment retrofitting.

Reliability Testing & Certifications

Every unit undergoes:

· Type test verification per IEC 60034 standards

· Temperature rise testing under rated load conditions

· Insulation resistance and hi-pot testing

· Vibration analysis across operational speed range

· Explosion-proof joint gap verification

We have CCC, CE, ISO9001:2000, CRCC, CQC, ZDHY, UL and GOST certificates which are the worldwide safety and quality certifications.

FAQ

Q：What is YBX5 motor, and what energy efficiency standard does it reach?

A：YBX5 is the latest generation IE5 ultra-premium efficiency flameproof three-phase asynchronous motor, upgraded from YBX4 series. It meets Class 1 energy efficiency of GB 18613-2020 and IEC 60034-30-1 IE5 standard—the highest efficiency grade currently available.

Q：What explosion-proof marks does YBX5 have?

A: The standard markings are Ex d I Mb (for underground coal mine) and Ex d ⅡA/ⅡB/ⅡC T4 Gb (for factory Zone 1 & Zone 2 area with flammable gas such as methane, ethylene, hydrogen, etc.).

Q：What is the difference between YBX5, YBX4 and YBX3?

A: YBX5 is IE5 efficient (4-7% better than YBX4 IE4), utilises better materials with better cooling, runs quieter with less vibration yet has the same mounting dimensions to replace YBX4 directly.

Q：Can TEFC motors be explosion-proof?

A：Standard TEFC motors are dust-tight but require additional modifications for explosion-proof certification. The product integrates flameproof construction from the design stage, ensuring compliance without aftermarket modifications.

Q：Which equipment commonly uses YBX5 motors?

A：They drive fans, water pumps, compressors, conveyors, mixers, crushers, and centrifuges in continuous operation scenarios requiring reliable performance in hazardous locations.
